X-Ray Tube Single Anode Bore

An x-ray source comprising:

• an x-ray tube including a cathode and an anode electrically insulated from one another, the cathode configured to emit electrons in an electron beam towards the anode, the anode including a target material configured to emit x-rays out of the x-ray tube in response to impinging electrons from the cathode, the target material and the anode comprise tungsten and lanthanum oxide;
• a heat sink thermally coupled to the anode, and extending away from the anode along a heat sink longitudinal axis;
• the heat sink having a base and a fin extending from the base;
• the base having a greater thickness nearer the anode and reducing in thickness along the heat sink longitudinal axis to a smaller thickness farther from the anode.
